My invention relates to photographic film. i

made from such negatives. T o facilitate this operation, the strips may be gummed at the back so that the notes only require moistening for pasting them to the negatives.

The areas f illustrated in Figs. 1-4 are comparatively small. It has been assumed that they will bear only a single note, as a rule, a note relating to the subject of the picture. For instance the name of a person in the case of a portrait, the name of a scene or a building, or whatever it may be, is copied on the prints taken from a given negative. However, it may be desirable for the operator to make and to keep other notes which are of interest only to himself and this obviously requires a larger area. An example for a principal strip 6 with areas for several notes is illustrated in Figs. 5, 6 and 7.

The strip e is attached to the wrapper b by means of an adhesive sticker 0 with which it is connected by perforations (Z, as described with reference to Figs. l4. In addition, it may havean adhesive sticker n at its free end with perforations (P. The marks 70, la and 11 are ap lied to the wrapper and the film as describe and, in addition, numerals i are inserted in the several. areas of the strip which correspond to the numerals 1: on the wrapper and, obviously, to the numerals h on the film a.

As mentioned, generally only the note of the subject will be copied on the pictures while the other notes are of private interest only. Therefore, as illustrated for the picture (2), the area which is reserved for the subject is surrounded with perforations, or is otherwise so connected with the strip as to be readily detached therefrom. Obviously, a slip which is detached in this manner should be transparent. Generally, it will be found convenient to make the film of transparent material throughout, but obviously the area within the perforations might be separately prepared so as to make it transparent. The slip within the perforations should also be gummed and for the sake of simplicity it will enerally be preferred to make the strip with its stickers of gummed material throughout instead of applying adhesive to the stickers and the subject areas only.

It will he understood that the strip within the perforations is lost to the operator who is therefore under the necessity of making a separate note about the subject. This drawback is eliminated by the expedient illustrated in Fig. 7. Here, a slip 0 of transparent and preferably gummed paper is pasted to the area of the strip 6 opposite the area for the subject, or any other area from which a The slip 0 is attached to the strip e along its edges only so as to form a pocket, as best seen in Fig. 7, and a strip of carbon paper 0 is inserted between the strip e and the slip 0, with its layer facing the slip. In this manner a note which is made in the area for the subject is copied on the slip 0 which is then separated from the stri e and pasted to the negative. Instead o inserting a strip of carbon paper at the area of the subject the slip 0 might be provided with a layer of carbon or the like p at its back, as illustrated in Fig. 8. In this manner the note of the subject, or any other note or notes, may be preserved on the strip e while the slip 0, with the same note on it, is pasted to the negative.

The sections marked 1, 2, etc., are all similar although the printed matter has been omitted except in sections 3, 4, etc., to save unnecessary labor.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a person skilled in the art.
